Are you sure? Did you try? Just run that gcc with:
  ...toolchain/powerpc-unknown-linux-gnu/bin/gcc -v
and see what it says...

Anyway, those are internal executables, don't mess with them!
The ones that matter are in "...toolchain/bin", as you discovered
initially.

It is needed to _run_ the 'powerpc-unknown-linux-gnu-g++' program.

Just run: ldd ...toolchain/bin/powerpc-unknown-linux-gnu-g++
and see what libraries it is looking for, and which are missing.

Did you move your toolchain from one machine to another ?
